Coastal Key WordsBay: A Broad coastal inlet usually with a beachAbrasion: A process of erosion where rocks get hurled at the coastline by wavesAttrition: A process of erosion where rocks collide and parts break off leaving smallerrocksBar: A spit that has grown across a baySpit: A finger of new land made of sand or single jutting out into the sea from the coast.Longshore Drift: The zig-zag movement of beach material along a coastlinePrevailing Wind: Dominant Wind, South Westerly in the UKHydraulic Action: Air forces cracks in rocks apartCorrosion: Erosion by acids within the sea.Weathering: The break up or decay of rocks on the earths surface.Headland: A Promontory of land jutting out into the sea.…read more

Slide 3

Onion Skin WeatheringWhere Does it Occur?Above water and normally in hot and cold places such as DesertsWhat does it need to happen?Hot and Cold weather changing in temperature. Increasing and Decreasing rapidlyWhat Rock Does it Effect?Rocks which occur in layers ( Metamorphic: Slate )How Does it Break the Rock down?The rock in hot weather (daytime) expands and in the cold weather (nightime) itcontracts, this weakens the rock.…read more

Slide 4

Biological WeatheringWhere Does This Happen?Usually on the top of a cliff where vegetation and animals have access to the rockWhy Does it Happen?Animals and Vegetation bury into the rock with plants roots, and animals natural habitatWhat Type Of Rock Does It Occur?Soft Rocks, Such as Limestone (they are softer and easy to penetrate)How Does it Break It Down?The roots create cracks in the rock therefore weakening it, and animals bury into the groundlooking for food etc, which weakens it more. This then leads to other weathering.…read more

Slide 5

Freeze Thaw WeatheringWhere does it Happen?Cracks in the cliff where the temperature drops below freezing at nightWhy does it Happen?Water gets into cracks, sometimes from the sea, or from the rain, when it gets to belowfreezing over night this water then expands when it freezes and forces the crack biggerWhich Type Of Rock?Any, it occurs mainly on rocks which have had cracks in them due to other weathering.How does it break it Down?The water freezes inside the crack and forces the crack bigger, this then weakens the rockand leads to the rock being unsteady.…read more

Slide 6

Chemical WeatheringWhere Does it Happen?Mainly on the top of a cliff, Anywhere the is pollutionWhy does it Happen?The pollution from factories etc can cause acid rainWhat type of Rock?Limestone is very vulnerable, statues and some older buildings are made from this. Limestoneis a soft rock.How does it Break it down?The acidic content causes it to corrode. This could eventually over time change the propertiesof the statue or building and in 100s of years vanish it completely.…read more
